Figure 35
4,4′-Dichlorobenzophenone – dependence of the intensities of representative reflections on temperature. The upper diagram shows the heating and cooling curves for the 111 reflection present in the higher-temperature C2/c phase and absent in the lower-temperature I2/c phase. The converse applies to the 031 reflection. Each pair of heating–cooling curves follows the pattern of Fig. 4[link], but the mean temperatures, which would be expected to approximate to T0 for the system, are displaced by about 8 K.
